Its story

55 Persei is a blue-white B8V star about 448 light-years away, with around 3.4 solar masses and roughly 116 times the Sun's luminosity. It burns above twelve thousand kelvin, the temperature of the youngest and most energetic main-sequence stars. Quiet to the eye, it belongs to the hot family that frames Perseus —the mythological hero who beheaded Medusa and rode Pegasus across the night sky.
